Something new / Puncture Proof / self-healing pneumatic bicycle tires. Nails, tacks, glass, etc. will not let the air out. One pair for only $4.75, which was a gigantic amount of money in 1901. Still, have we lost the technology to make these??!? Published in the April 25, 1901 issue of THE YOUTH'S COMPANION.
